Radial Interstices Enable Speedy Low-volume Imaging
• Standard MRI methods acquire Fourier-encoded data on a regularly spaced Cartesiangrid. Noncartesian MRI methods abandon this grid and instead acquire data alongarbitrary trajectories in k-space, which can lead to advantages such as motion robustnessand more flexible pulse sequence design.• Zero Echo Time (ZTE) imaging is a specialised form of MRI with an inherently noncartesian three-dimensional
